Fig 1.
Peripapillary capillary density maps.
Comparisons of peripapillary capillary density maps in a normal, an anterior ischemic optic neuropathy (AION) eye with average retinal nerve fiber layer (RNFL) thickness of 54 μm and visual field mean deviation of -20.5 dB, and a severe primary open-angle glaucoma (POAG) eye with average RNFL thickness of 49 μm and mean deviation of -25.2 dB. First column: grayscale OCT-A images with two concentric circles with 1.95-mm (inner) and 3.45-mm (outer) diameters, Second column: Perfused capillary area (in cyan) after the removal of major blood vessels. Third column: corresponding color-coded perfused capillary density maps with numerical capillary density (%) in peripapillary ring in four quadrants.
